    Introduction: Differences in the trajectory of non-motor symptoms (NMS) between male and female Parkinson's disease (PD) patients over the course of the disease are not well-understood. Methods: PD patients were rated with Non-Motor Symptom Scale (NMSS) at two time points with a median follow-up of 3.8 years (IQR 2.1–5.6 years). Sex, age, disease duration, Unified Parkinson's Disease Rating Scale and doses of PD-related medication were registered. Linear mixed models (LMMs) and multinomial logistic regression (MLR) models were fitted to explore the association of sex with changes in NMSS domains over time. Results: Eighty-seven PD patients (30 females and 57 males) were enrolled. Baseline demographic and clinical characteristics were similar between female and male PD patients. The mean increase in NMS frequency and severity over time was non-significant, as well as the interaction term for disease duration × sex. However, gastrointestinal symptoms worsened in both males and females. According to the minimal detectable change of NMSS, <50% of PD patients experienced changes at follow-up beyond measurement error of the scale. Male sex predicted sexual function worsening (adjusted OR = 10.1, p = 0.038). Also, PD patients with more severe symptoms at baseline had increased odds of improving over time. However, high initial scores in attention/memory and cardiovascular domains also posed individuals at a higher risk of symptom worsening (OR [95% CI] = 1.4 [1.0-1.8], p = 0.034 and OR [95% CI] = 2.1 [1.2-3.7], p = 0.01, respectively). Conclusion: NMS progression over the disease course in PD shows large inter-individual variability without observable effect of sex.
